T0 atZZ whom it may concern:

Be it known that I, JAMES SPEIGHT SMITH, a citizen of the United States,residing at Chicago, county of Cook,- and State of Illinois, haveinvented an Adj ustable Striking-Plate for Door-Jambs, of which thefollowing is a specification.

This invention relates to an improved adj ustable striking-plate fordoor locks and jambs, and has for its object to provide a simple and.convenient device of this kind that can be used either as a right orleft plate.

Figure 1 is a elevation of a device embodying the improved features.Fig. 2 is a similar view with the adjustable plate removed. Fig. 3 is anelevation of the removed adjustable plate; and Fig. 4 is a transversesection on line 4, Fig. 3, looking in the direction indicated by thearrow.

The device consists of the stationary strike- 7 plate A and theadjustable plate or slide B, framed therein the joining edges beingsmooth. The stationary plate A is provided in its respective ends withthe screw-holes a, for the insertion of the usual screws in securingthesame to the jainb ordoor-frame. This plate is provided longitudinallywith a slotopening a, stopping short of the respective ends. Thestrike-plate is also provided with the cross-bars C O, havinga boss orswell a on the rear side thereof, Fig. 4, forming a seat for thecompanion adj ustingscrews a o which are inserted through the elongated.apertures b b in the adjustable plate and the holes d ml in thecross-bars O .G. In this form of construction the adj usting-screws a ado not enter the wood of the j amb, but end in the boss a and may betermed a righthand plate only. I

When thedevice is to be reversible, so as to be used either as a rightor left hand plate,

the cross-bars C O aredispensed with, thus adapting-the plate to be usedon eitherside of the door, the adjustingscrews seating in the wood ofthe jamb,

The stationary plate is permanently secured in place, the adjustableplate being framed therein and movable endwise, either up or down,inbringing the same into position to receive the latch and bolt of thedoor-lock.

The movable plate'is locked in the position to which it is capable ofbeing adjusted by means of the screws a a The stationary plateisprovided with the usual projection c which receives the impact of thelatch; The openings h and h in the adjustable plate. receive the latchand locking-bolt, respectively. This ar ranger'nent dispenses with I thenecessity of moving the strike-plate proper and leaving an unsightlycut-off recess either above or below the same. The movable plate iseasily and quickly adjusted as the varying conditionsof vadjustableplate, framed therein and having elongated apertures near the respectiveends thereof, and Ineansfor holding the movable plate in any position towhich it may be adjusted, substantially as described.
